I would find it useful to be able to select multiple cards and Status stamp or Label them all at one go. Perhaps there is some way of doing this I just have not figured out yet.
You can do this by selecting files in the Binder, rather than on the corkboard, and using either the menu commands or contextual menu to apply the label/status you desire.
Thanks for that. Seem to learn something new about Scrivener every day. 
Don’t be embarrassed, it took me a while to figure that one out, too
